Why Everyone Should Learn the Theory of Evolution

 
Why Everyone Should Learn the Theory of Evolution is the title of an editorial on the Scientific American website.

The editors begin by pointing out that Charles Darwin was a genius who deserves every bit as much recognition as Albert Einstein. I agree 100%. In my opinion Darwin is the greatest scientist who ever lived and it's about time we started to recognize his genius.

The rest of the editorial isn't as good. It's clear that the editors have a myopic view of evolution. They seem to think that the sort of evolution everyone should learn can be found in The Origin of Species.

But Darwin is so much more than just a quaint, Victorian historical figure whose bust in the pantheon deserves a place among those of other scientific greats. Theory needs to explain past, present and future—and Darwin’s does all three in a form that requires no simplifying translation. His theory is readily accessible to any literate person who allots a pleasurable interlude for On the Origin of Species, its prose sometimes bordering on the poetic: “... from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”

Now, you can learn a lot about evolution from reading Darwin's 1859 book. You can learn, for example, about natural selection and you can also learn about the inheritance of acquired characteristics.

You won't learn anything about genetics or biochemistry or developmental biology or bacteria or genomes or whether birds are related to dinosaurs.

The editors link to another article published in this month's Scientific American: The Evolution of Evolution. The article by Gary Stix attempts to explain Darwin's Living Legacy--Evolutionary Theory 150 Years Later. It doesn't do a very good job but at least it raises some interesting questions.

The concept of evolution as a form of branching descent from a common ancestor achieved a relatively rapid acceptance, but accommodation for natural selection came much more slowly, even within the scientific community. The hesitation was understandable. In his work, Darwin had not described a mechanism for inheritance, attributing it to minuscule, hypothetical “gemmules” that ejected from each tissue and traveled to the sex organs, where copies were made and passed to subsequent generations. It took until the decades of the 1930s and 1940s for natural selection to gain broad acceptance.

It was then that the modern synthesis emerged as an expansive framework that reconciled Darwin’s natural selection with the genetics pioneered by Gregor Mendel. In 1959, the centennial of the publication of Origin of Species, the place of natural selection seemed assured.

But in the ensuing years, the scope of evolutionary biology has had to broaden still further to consider such questions as whether the pace of evolution proceeds in fits and starts—a paroxysm of change followed by long periods of stasis. Do random mutations frequently get passed on or disappear without enhancing or diminishing fitness, a process called genetic drift? Is every biological trait an evolutionary adaptation, or are some characteristics just a random by-product of a physical characteristic that provides a survival advantage?

The field has also had to take another look at the notion that altruistic traits could be explained by natural selection taking place across whole groups. And as far as the origin of species, what role does genetic drift play? Moreover, does the fact that single-celled organisms often trade whole sets of genes with one another undermine the very concept of species, defined as the inability of groups of organisms to reproduce with one another? The continued intensity of these debates represents a measure of the vigor of evolutionary biology—as well as a testament to Darwin’s living legacy.

We know the answers to some of these questions. The modern version of evolution is the one that everyone should learn—not the 150-year-old version that Darwin wrote about.

If the editors of Scientific American don't understand the difference then our society is in a lot worse trouble than I imagined.

Monday's Molecule #101

 
This is the last Monday's Molecule for 2008. There will be a short Christmas break. Monday's Molecule will return on January 5th. As part of the Christmas celebrations, this week's molecule is a gift.

Your task is to identify this molecule and give it a biochemically accurate name (the IUPAC name would be perfect). The Nobel Laureate should be obvious once you identify the molecule.

The first one to correctly identify the molecule and name the Nobel Laureate, wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first collected the prize.

There are four ineligible candidates for this week's reward: Ms. Sandwalk from Mississauga, Ontario, Canada, Alex Ling of the University of Toronto, Timothy Evans of the University of Pennsylvania, and John Bothwell of the Marine Biological Association of the UK in Plymouth, UK. John, Dale and Ms. Sandwalk have offered to donate the free lunch to a deserving undergraduate so the next two undergraduates to win and collect a free lunch can also invite a friend. Alex got the first one.

THEME:

Nobel Laureates
Send your guess to Sandwalk (sandwalk (at) bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the "molecule" and names the Nobel Laureate(s). Note that I'm not going to repeat Nobel Laureate(s) so you might want to check the list of previous Sandwalk postings by clicking on the link in the theme box.

Correct responses will be posted tomorrow. I reserve the right to select multiple winners if several people get it right.

Comments will be blocked for 24 hours. Comments are now open.

UPDATE: The molecule is 2&prime,3′-dideoxycytidine 5′-monophosphate. This molecule differs from the normal cellular version of deoxycytidine because it is missing a second hydroxyl group at the 3′ position on the sugar. The triphosphate version of this molecule is a substrate for DNA polymerase and it will be incorporated into a growing DNA chain. However, once it is incorporated, the polymerization reaction stops because the 3′ hydroxyl group is essential for addition of the next nucleotide.

Dideoxynucleotides are used in the chain termination method of DNA sequencing developed by Frederick Sanger. Sanger received his second Nobel Prize in 1980 for developing this method, which remains the most popular method of DNA sequencing.

I was surprised that only a few people responded and even more surprised that some of the regulars didn't give a correct name for this molecule. There is no winner this week because I am being strict about nomenclature. If you didn't specify where the phosphate is attached (5′) or you used "cytosine" instead of "cytidine," then you don't get a free lunch! (Cytosine is the base, cytidine is the nucleoside.)

Conservatives Condone Torture, Liberals Don't

 
Let me make this perfectly clear—in my opinion, any society that condones and practices torture is a society in which the rights of all individuals are diminished. The rights of individuals and the goal of a just society are qualitative traits, not quantitative traits. If some people are deprived of those rights and if some people aren't part of the just society, then the "rights" don't exist and the society is not just. You can't have the right to fair treatment under the law in some situations but not in others. That's a mockery of justice.

Reuel Marc Gerecht is a former Central Intelligence Agency officer and a fellow at the Foundation for Defense of Democracies (FDD). The leadership of FDD consists of people like Newt Gingrich, Bill Kristol, Steve Forbes, and Joe Lieberman. They are "small-c" conservatives. Mostly Republicans, I think (including Lieberman, the Republican-in-all-but-name).

Last Saturday Gerecht wrote an opinion piece in The New York Times in defense of torture [Out of Sight].

He starts off by defending extraordinary rendition. This is the tactic of sending suspected criminals to other countries where they can be tortured and then returned to the USA. The idea is to be able to deny that the USA is in violation of its own Constitution and respect for human rights.

Mr. Obama will soon face the same awful choices that confronted George W. Bush and Bill Clinton, and he could well be forced to accept a central feature of their anti-terrorist methods: extraordinary rendition. If the choice is between non-deniable aggressive questioning conducted by Americans and deniable torturous interrogations by foreigners acting on behalf of the United States, it is almost certain that as president Mr. Obama will choose the latter.

Aside from the fact that torture is legally and ethically wrong, there's three other slight problems with this tactic. First, who are they trying to deceive? Is there anyone with an IQ over 50 that can be fooled by extraordinary rendition?¹ Second, there's very little evidence that torture works. Third, many innocent people have been tortured.

Canada is particularly sensitive about rendition because of Maher Arar. Arar, a Canadian citizen, was arrested in 2002 at Kennedy Airport in New York and send to Syria where he was tortured and confined for 10 months. He was subsequently released and the Canadian government has established that he is innocent [Canadian cleared of terrorism after rendition, torture in Syria].

We don't know how many other innocent people have been tortured but chances are the numbers are substantial. The problem with rendition is that the individuals are deprived of their right to face their accusers and prove their innocence. No respectable society should condone such behavior.

Gerecht then raises the standard canard that seems to be the last refuge of those who would violate people's rights.

However, troubles in Pakistan may well reverse Mr. Obama’s luck. He has said he intends to be hawkish about fighting Al Qaeda and the Taliban in Central Asia. So, let us suppose that he increases the number of Special Forces raids into Pakistan, and those soldiers capture members of Al Qaeda and their computers, and learn that the group has advanced plans for striking American and European targets, but we don’t know specifically where or when.

What would Mr. Obama do? After all, if we’d gotten our hands on a senior member of Al Qaeda before 9/11, and knew that an attack likely to kill thousands of Americans was imminent, wouldn’t waterboarding, or taking advantage of the skills of our Jordanian friends, have been the sensible, moral thing to do with a holy warrior who didn’t fear death but might have feared pain?

No, Mr. Gerecht, torture is not a sensible, moral thing to do. It is stupid and immoral.

Stupid because the chances of finding out useful information under such circumstances are slim to zip. Stupid because under the Golden Rule we are putting the lives of all of our citizens at risk when they are captured by the bad guys. Stupid because it is contrary to the very thing that we are supposed to be fighting for. Stupid because the Americans who carry out rendition can be, and should be, put in jail. (I would even advocate that those who advocate breaking the law as almost as guilty.)

Immoral because .... never mind, he wouldn't know morality if it bit him on the posterior.

This issue is important in Canada for another reason. Our recently appointed Liberal leader, Michael Ignatieff, has a somewhat checkered history of modest support for torture. Recently his writings have been more clear about his opposition to torture while pointing out the moral dilemma [If torture works ...]. I'm going to quote extensively from his essay because this is a man who will be Prime Minister of Canada.

It is difficult to think about torture honestly. In a recent article on the interrogation techniques employed by the US, the writer Mark Bowden observed that few "moral imperatives make such sense on a large scale, but break down so dramatically in the particular." The moral imperative—do not torture, any time, anywhere, in any circumstances—is mandated by the UN convention against torture and other cruel, inhuman or degrading treatment or punishment. "No exceptional circumstances whatsoever, whether a state of war or a threat of war, internal political instability or any other public emergency," says the convention, can "be invoked as a justification of torture." That terrorists themselves torture does not change these imperatives. Our compliance does not depend on reciprocity.

.....

Elshtain justifies coercive interrogation using a complex moral calculus of "dirty hands": good consequences cannot justify bad acts, but bad acts are sometimes tragically necessary. The acts remain bad, and the person must accept the moral opprobrium and not seek to excuse the inexcusable with the justifications of necessity.

My own work on "lesser evils" brings me close to the Elshtain position. I agree with her that necessity may require the commission of bad acts, which necessity, nevertheless, cannot absolve of their morally problematic character—but I still have a problem. If one enumerates the forms of coercive interrogation that have been judged to be inhuman and degrading by the Israeli and the European courts—hooding, holding subjects in painful positions, exposing them to cold or heat or ear-splitting noise—these techniques also seem unacceptable, though at a lower threshold of awfulness, than torture. Like Elshtain, I am willing to get my hands dirty, but unlike her, I have practical difficulty enumerating a list of coercive techniques that I would be willing to have a democratic society inflict in my name. I accept, for example, that a slap is not the same thing as a beating, but I still don't want interrogators to slap detainees because I cannot see how to prevent the occasional slap deteriorating into a regular practice of beating. The issue is not, as Elshtain implies, that I care overmuch about my own moral purity but rather that I cannot see any clear way to manage coercive interrogation institutionally so that it does not degenerate into torture.

So I end up supporting an absolute and unconditional ban on both torture and those forms of coercive interrogation that involve stress and duress, and I believe that enforcement of such a ban should be up to the military justice system plus the federal courts. I also believe that the training of interrogators can be improved by executive order and that the training must rigorously exclude stress and duress methods.

Two significant problems remain. First of all, there is the problem of the exceptional case, one where lives can be saved by the application of physical methods that amount to torture. "Ticking bomb cases" cannot be wished away. They might arise especially where an American or European city faced the threat of WMD. An outright ban on torture and coercive interrogation leave a conscientious security officer with little choice but to disobey the ban. In this event, as the Israeli supreme court has said, even a conscientious agent acting in good faith to save lives should be charged with a criminal offence and be required to stand trial. At trial, a defence of necessity could be entered in mitigation of sentence, but not to absolve or acquit. This is the only solution I can see that remains consistent with an absolute ban on torture and coercive interrogation. Let us not pretend that the enforcement of this rule would be easy. Where the threat could be shown to be genuine, it seems evident that few legal systems would punish such a conscientious offender. So an outright ban on torture creates the problem of the conscientious offender. This is a small price to pay for a ban on torture.

Does an outright ban on torture and coercive interrogation meet the test of realism? Would an absolute ban on torture and coercive interrogation using stress and duress so diminish the effectiveness of our intelligence-gathering that it would diminish public safety? It is often said—and I argued so myself—that neither coercive interrogation nor torture is necessary, since entirely lawful interrogation can secure just as effective results. There must be some truth to this. Israeli interrogators have given interviews assuring the Israeli public that physical duress is unnecessary. But we are grasping at straws if we think this is the entire truth. As Posner and others have tartly pointed out, if torture and coercion are both as useless as critics pretend, why are they used so much? While some abuse and outright torture can be attributed to individual sadism, poor supervision and so on, it must be the case that other acts of torture occur because interrogators believe, in good faith, that torture is the only way to extract information in a timely fashion. It must also be the case that if experienced interrogators come to this conclusion, they do so on the basis of experience. The argument that torture and coercion do not work is contradicted by the dire frequency with which both practices occur. I submit that we would not be "waterboarding" Khalid Sheikh Mohammed—immersing him in water until he experiences the torment of nearly drowning—if our intelligence operatives did not believe it was necessary to crack open the al Qaeda network that he commanded. Indeed, Mark Bowden points to a Time report in March 2003 that Sheikh Mohammed had "given US interrogators the names and descriptions of about a dozen key al Qaeda operatives believed to be plotting terrorist attacks." We must at least entertain the possibility that the operatives working on Sheikh Mohammed in our name are engaging not in gratuitous sadism but in the genuine belief that this form of torture—and it does qualify as such—makes all the difference.

If they are right, then those who support an absolute ban on torture had better be honest enough to admit that moral prohibition comes at a price. It is possible, at least in theory, that subjecting interrogators to rules that outlaw torture and coercive interrogation, backed up by punishment if they go too far, will create an interrogation regime that allows some interrogation subjects to resist divulging information and prevents our intelligence services from timely access to information that may save lives.

If there is a significant cost to an outright ban on coercive interrogation and torture, what can possibly justify it? Many of the arguments that human rights activists make in justification amount to the claim that torture shames their moral identity as human beings and as citizens, and that they do not wish such acts to be committed in their names. Other citizens in a democracy may not value their own moral scruple over the collective interest in having accurate security information, even if collected by dubious means. It may be obvious to human rights activists how to adjudicate these claims, but it is not obvious to me. That is, I do not see any trumping argument on behalf of the rights and dignity of security detainees that makes their claims prevail over the security interests (and human right to life) of the majority. The best I can do is to relate the ban on torture to the political identity of the democracies we are trying to defend—by claiming that democracies limit the powers that governments can justly exercise over the human beings under their power, and that these limits include an absolute ban on subjecting individuals to forms of pain that strip them of their dignity, identity and even sanity.

We cannot torture, in other words, because of who we are. This is the best I can do, but those of us who believe this had better admit that many of our fellow citizens are bound to disagree. It is in the nature of democracy itself that fellow citizens will define their identity in ways that privilege security over liberty and thus reluctantly endorse torture in their name. If we are against torture, we are committed to arguing with our fellow citizens, not treating those who defend torture as moral monsters. Those of us who oppose torture should also be honest enough to admit that we may have to pay a price for our own convictions. Ex ante, of course, I cannot tell how high this price might be. Ex post—following another terrorist attack that might have been prevented through the exercise of coercive interrogation—the price of my scruple might simply seem too high. This is a risk I am prepared to take, but frankly, a majority of fellow citizens is unlikely to concur.

I'm more skeptical than Ignatieff about the efficacy of torture. Just because lots of people do it does not sound like a good argument for defending the usefulness of torture.

Nevertheless, when it comes to the bottom line, I'm with Michael Ignatieff, "We cannot torture ... because of who we are." If there's a price to be paid for doing the right thing then I'm prepared to pay it and suffer the consequences.

Women of The View Discuss Evolution

 
PZ Myers posted this on Pharyngula but in case some of you haven't seen it there, I though I'd post it too.

I find it really shocking that people would talk like this on television knowing that they're being watched by millions of people. Surely they realize that what they're saying conflicts with the consensus among scientific experts? I can understand how they might justify their anti-science position in their own minds in the privacy of their church or home but in public?

They must have a very low opinion of scientists.

Scientific American: The Evolution of Evolution

 
The latest edition of Scientific American is all about "The Evolution of Evolution."

Here's how the editor-in-chief, John Rennie introduces the articles.

When Charles Darwin published "On the Origin of Species" in 1859, he touched off a Cambrian explosion in evolutionary thought. Naturalists had theorized about evolution for centuries before him, but their ideas were generally unfruitful, untestable or wrong. Darwin's breakthrough insight was not that a simple mechanism—natural selection—made evolution possible. Rather it was that in organisms whose environments changed nonrandomly and whose reproductive success in that environment depended on inherited traits, evolution became inevitable.

In the decades that followed, Darwin's ideas connected up with the nascent field of genetics and then, at an ever quickening pace, with molecular biology, ecology and embryology. The explanatory power his concepts proved irresistible. Today 200 years after his birth and 150 years after "Origin of Species," Darwin's legacy is a larger, richer, more diverse set of theories than he could have imagined.

You will enjoy reading the articles to see exactly what Scientific American means when they talk of a "richer, more diverse set of theories." Here's the list.

Epigenetics at SEED

Epigenetics is one of the latest fads in biology. It arises out of evo-devo and its proponents tell us that epigenetics will transform the way we think about evolution. I've been trying to understand this phenomenon starting with some simple questions about what, exactly, is so new. I'd be happy if someone could just explain what they mean by "epigenetics" [Epigenetics in New Scientist, Epigenetics Revisited, Epigenetics, Epigenetics Again].

Eva Jablonka is a Professor at the Cohn Institute for the History and Philosophy of Science and Ideas at Tel-Aviv University (Israel). Jablonka was one of the 16 people who met in Alterberg, Austria last summer to discuss the faults in modern evolutionary biology. She writes an article entitled "Extending Darwinism" in the latest issue of SEED magazine.

I and several other biologists believe the MS [Modern Synthesis¹] is in need of serious revision. Growing evidence indicated that there is more to heredity than DNA, that heritable non-DNA variations can take place during development, sometimes in response to an organism's environment. The notion of soft inheritance is returning to reputable scientific inquiry. Moreover, there seem to be cellular mechanisms activated during periods of extreme stress that trigger bursts of genetic and non-genetic heritable variations, inducing rapid evolutionary change. These realizations promise to profoundly alter our view of evolutionary dynamics.

Nothing new here, folks. It's just the same old gibberish that we've been hearing for the past several years.

If there is as much natural variation induced by environmental factors as lab studies suggest, then rapid evolutionary change could occur without any genetic change at all.

Eva Jablonka
But there is one thing that's worth noting. Eva Jablonka has done what few of her fellow epigeneticists have attempted. She defines what she means by epigenetics!

Epigenetics is a term that includes all the processes underlying developmental flexibility and stability, and epigenetic inheritance is part of this. Epigenetic inheritance is the transmission of developmental variations that have nothing to do with changes in the DNA base sequences. In its broad sense, it covers the transmission of any differences that do not depend on gene differences, so it encompasses the cultural inheritance of different religious beliefs in humans and song dialects in birds. It even includes the developmental legacies that a young mammal may receive from its mother through her placenta or milk—transmitted antibodies, for example, or chemical traces that tell the youngsters what the mother has been eating and, therefore, what they should eat.

Yes, but does it include the kitchen sink?

The good thing about incorporating these things into evolutionary theory is that it solves the problem of creationism. As long as creationism is passed on from parent to child then it becomes part of evolution. Isn't that cool?

A Holy Alliance?

 
Mario Beauregard is an Associate Researcher in the Departments of Radiology and Psychology at the University of Montreal in Montreal, Quebce, Canada. He is best known as the co-author of The Spiritual Brain with Denyse O'Leary.

Jeffrey M. Schwartz is a research psychiatrist at the School of Medicine at the University of California at Los Angeles (USA). He signed the Discovery Institute's "Scientific Dissent from Darwinism" statement.

Beauregard and Schwartz joined in a holy alliance to write a letter of protest to New Scientist concerning an article published a few months ago. The article was critical of people like Beauregard and Schwartz who mix religion and science.

Your writer's attempt to smear scientists who are looking for new directions, while perhaps entertaining, is a poor substitute for thoughtful coverage of a growing area.

Perhaps we should be looking to writers like Denyse O'Leary for thoughtful coverage?

[Hat Tip: A Blog Around the Clock]

Does Your Heart Bleed for Jodi?

 
Times are tough these days. People have lost their jobs and many are struggling to put food on the table and keep a roof over their heads. Christmas is not going to be a happy time in many households across North America.

The New York Times, bless its heart, is not unaware of what's going on. Lisa Foderaro has written an article that's sure to bring a tear to your eye as she documents the devastating effect of job loss on the life of a teenager [As the Rich Get Poorer, Teenagers Feel the Crunch ].

Jodi Hamilton began her senior year of high school in Woodcliff Lake, N.J., this fall on the usual prosperous footing. Her parents were providing a weekly allowance of $100 and paying for private Pilates classes, as well as a physics tutor who reported once a week to their 4,000-square-foot home.

But in October, Jodi’s mother lost her job managing a huge dental practice in the Bronx, then landed one closer to home that requires more hours for less money. Pilates was dropped, along with takeout sushi dinners, and Jodi’s allowance, which covers lunch during the week, slipped to $60. Instead of having a tutor, Jodi has become a tutor, earning $150 a week through that and baby-sitting.

“I just thought it would be responsible to get a job and have my own money so my parents didn’t have to pay for everything,” said Jodi, who is 17. “I always like to be saving up for something that I have my eye on — a ring, a necklace, a handbag.”

Later on in the article we hear about some other teenagers who have been forced to find a job.

Teenagers from working- and middle-class families are, of course, feeling similar — if not more acute — pressure. Sumit Pal, 17, a senior at Information Technology High School in Queens, said his parents cut his $5 weekly allowance two months ago after the deli where his father works started to lose business. Sumit was interviewed two weeks ago for a job at a company that sponsors rock bands.

“I don’t mind losing my allowance,” he said. “It goes toward other things, like groceries.”

How nice of Ms. Foderaro to mention that the lower classes are also, "of course," feeling the pinch.

What Is the Scientific Method?

 

There are lots of interesting things in this month's issue of SEED magazine. One of them is a survey of scientists in the USA, UK, France and Germany.

SEED magazine conducted a survey where it asked the following question of 1000 scientists in the USA, UK, France, and Germany: "Does the scientific method describe how you do science?" [SEED: State of Science].

81% said "yes."

I would answer "no" but my answer depends very much on what I think the question means. I think it's fair to use the common understanding of the "scientific method," the one that's taught in fifth grade.

Here's the simple version that's described on the Wikipedia site [Scientific Method].

1. Use your experience: Consider the problem and try to make sense of it. Look for previous explanations. If this is a new problem to you, then move to step 2.
2. Form a conjecture: When nothing else is yet known, try to state an explanation, to someone else, or to your notebook.
3. Deduce a prediction from that explanation: If you assume 2 is true, what consequences follow?
4. Test : Look for the opposite of each consequence in order to disprove 2. It is a logical error to seek 3 directly as proof of 2. This error is called affirming the consequent.

Is this what most people think about when they hear the term "scientific method"?

If you are a scientist, how would you have answered the SEED question and what definition of "scientific method" do you have in mind?

Religious Scientists

 
There are lots of interesting things in this month's issue of SEED magazine. One of them is a survey of scientists in the USA, UK, France and Germany.

SEED asked a total of 1000 scientists whether they were "atheist or agnostic," "practicing nonbelievers," "believers," or "spiritual" [SEED: State of Science].

Here's the result, in percent, for each of the four choices.

USA: atheist = 17%, nonbelievers = 6%, believers = 53%, spiritual = 24%
UK: atheist = 44%, nonbelievers = 10%, believers = 35%, spiritual = 11%
France: atheist = 50%, nonbelievers = 6%, believers = 39%, spiritual = 5%
Germany: atheist = 40%, nonbelievers = 24%, believers = 32%, spiritual = 4%

I find this surprising. The distribution isn't that much different from the general public in each of the countries. I was under the impression that scientists are considerably less religious than the society in which they live.

Perhaps this is because the SEED definition of scientist is more flexible than the one I would use. Here's the breakdown of their survey group.

Social Science: 24%
Medicine: 23%
Life Sciences: 15%
Engineering: 12%
Physical Sciences: 9%
Computer Science: 9%
Mathematics: 8%

Richard Cizik Resigns

 
Most of you have never heard of Richard Cizik. Let me explain why his resignation is important.

A few days ago I posted an opinion on framing and referred you to Matt Nisbet who claims that Richard Cizik is a good example of how to present science to the general public. Cizik is Vice President for governmental affairs of the National Association of Evangelicals (NAE). Nisbet thinks he is the top climate communicator [see Communicating the Truth about Climate Change].

I quoted from Nisbet's blog where he refers approvingly to a Cizik interview with Terry Gross.

Yesterday Christianity Today announced that Richard Cizik has been forced to resign his position in the National Association of Evangelicals [Richard Cizik Resigns from the National Association of Evangelicals]

Richard Cizik resigned Wednesday night as vice president for governmental affairs of the National Association of Evangelicals (NAE) during a week of growing uproar over his comments that he is shifting his views on same-sex unions.

"Although he has subsequently expressed regret, apologized, and affirmed our values, there is a loss of trust in his credibility as a spokesperson among leaders and constituencies," Leith Anderson, president of the NAE wrote to board members today. Cizik did not return calls for comment.

Last year, more than two dozen evangelical leaders sought to oust Cizik, who has been vice president for 28 years, because of his "relentless campaign" on global warming.

"For better or for worse, Rich became a great, polarizing figure," said Charles Colson of Prison Fellowship. "He was gradually, over a period of time, separating himself from the mainstream of evangelical belief and conviction. So I'm not surprised. I'm sorry for him, but I'm not disappointed for the evangelical movement."

Cizik spoke mostly on the environment in a December 2 interview with Terry Gross on National Public Radio's Fresh Air, but he made brief remarks about same-sex civil unions, gay marriage, and his early support of President-elect Barack Obama.

In a short portion of the program, Gross asked him, "A couple of years ago when you were on our show, I asked you if you were changing your mind on that. And two years ago, you said you were still opposed to gay marriage. But now as you identify more with younger voters, would you say you have changed on gay marriage?"

Cizik responded, "I'm shifting, I have to admit. In other words, I would willingly say that I believe in civil unions. I don't officially support redefining marriage from its traditional definition, I don't think."

I wonder if Matt still thinks that Richard Cizik is the best example of successful framing?

Noah's Ark

 
Yesterday I dropped a hint about a plastic model of Noah's Ark. I suggested it might make a good gift ... in case anyone was thinking about gifts.

Ms. Sandwalk was a bit insulted 'cause we already have a perfectly good ark that she made—complete with animals. Here's a photo of her work. I have to admit that it's a lot better than the plastic model.
